61DVD-2910/955Differential Signal Data PinsPin Name Pin # Type DescriptionTX0+TX0-TX1+TX1-TX2+TX2-252428273130AnalogAnalogAnalogAnalogAnalogAnalogTMDS Low Voltage Differential Signal output data pairs.These pins are tri-stated when PD# is asserted.TXC+TXC-2221AnalogAnalogTMDS Low Voltage Differential Signal output clock pairs.These pins are tri-stated when PD# is asserted.EXT_SWING 19 Analog Voltage Swing Adjust. A resistor should tie this pin to AVCC. This resistordetermines the amplitude of the voltage swing. A 510 ohm resistor isrecommended for remote display applications. For notebook computers, 680 ohmis recommended.Configuration/Programming PinsPin Name Pin # Type DescriptionMSEN 11 Out Monitor Sense. This pin is an open collector output. The output is programmablethrough the I 2C interface (see I 2C register definitions). An external 5K pull-upresistor is required on this pin.RESERVED 34 In This pin is reserved.NC 7,8 NC These pins are not electrically connected inside the package.Control PinsThese control pins allow configuration of the transmitter through the slave I2C port, which is required by HDCP.Pin Name Pin # Type DescriptionISEL/RST# 13 In I2C Interface Select. If HIGH, then the I 2C interface is active.SCLS 15 In DDC I 2C Clock.SDAS 14 In/Out DDC I 2C Data.CTL3 6 In External CTL3.HTPLG 9 In Monitor Charge Input. This pin is used to connect to the DVI Hot Plug pin to detectthe presence of an attached monitor.Power and Ground PinsPin Name Pin # Type DescriptionVCC 1,12,33 Power Digital VCC.
